Why should operators use SDN and NFV, How does this improve end user experience and Why is this a must have for 5G?
LTE Quality of service has been critical for the deployment of 4G based services. There are users who want to avail its basic services such as voice calls, banking transaction, etc, and there are users who want to avail the premium services such as high-speed internet downloads and streaming services.
By deploying NFV and SDN, the network operators are not supposed to use high cost proprietary hardware to provide chain of network. Also, cost reduction is very much important when we keep moving from one generation to another generation of technology advancement which utilizes minimum network bandwidth and boost latency.
This has made operators realise the demands for low cost and reliable connections. This can be only be overcome if we can break through the QoS limitations of the existing networking. After several failed attempts, SDN has emerged as a paradigm shift to provide the best user experience.
Using NFV and SDN makes the entire network modular and agile. SDN and NFV can deliver a consistent, reliable and high-quality experience to all users, which has a significant impact on the user experience and in turn, helps retain customers.
The world has seen a ton of innovation in the devices we use to access networks, the applications we use, the services we rely on in our daily lives, and the computing and storage solutions we use for “big data”. Software-defined network (SDN) and Network functions virtualization (NFV) provide us with new and robust ways to design and build networks.
SDN enables networks to be centrally controlled through software applications that use open APIs. NFV separates the network functions from the hardware components, so they can run in software. It virtualizes entire classes of function into smaller and modular building blocks that may be connected or chained together to create new services. SDN and NFV have become an attractive option for integrators and value-added resellers (VARs) that need strategies for network virtualization and network programmability.
